What a business may do with it
CopyleftGPL-3.0
Free to run in-house. Distribute it, or software built on it, and that source must be released under the GPL too.
This describes the licence family GitHub identified, not legal advice about this project. The repository’s own LICENSE file is what binds you.
Run it yourself
Kontalk’s README does not show a docker run, docker compose up or helm install in a code block, so this page will not guess one. It may be a desktop app, a library, or documented on its website.
